Saturation of peripheral oxygen (SpO2) is one of the most important parameters of vital signs. Pulse oximeter which based on near-infrared spectroscopy is commonly used as a non-invasive method to measure SpO2[1] ,Currently, medical device manufacturers as well as metrology measurement agencies in China usually use pulse oximeter simulator as the commonly accepted functional calibration equipme...

The use of a structured approach to production system design is an effective means to improve a firm’s overall manufacturing capability. Design of a production system in addition to defining system architecture (subsystem organization and integration) also includes allocating high-level system requirements to subsystems. An area where requirements allocation is critical to system performance is...

OBJECTIVES Identify radiographers' postures during frequent mammography procedures related to the mammography equipment and patient characteristics. METHODS A postural task analysis was performed using images acquired during the simulation of mammography positioning procedures. Simulations included craniocaudal/(CC) and mediolateral-oblique/(MLO) positioning in three different settings: radio...
